Definitions

  • the present invention relates to a polygonal construction panel, formed of a layer of substantially constant thickness of a rigid material and further comprising a network of interconnected bosses with hollow section intended to increase the rigidity and delimiting ranges, the density of distribution of the internal bosses being substantially constant at the surface of the panel.
  • a second plate provided with additional bosses may have a lower rigidity, the bosses intended to increase the rigidity being able, under conditions data, revealing themselves as weak zones allowing in particular a folding favoring a deformation mode of the plate.
  • the object of the invention is, by providing new stiffness criteria applicable a priori, and by proposing new construction characteristics, the production of new panels whose rigidity is greater than that of known panels, so that they are self-supporting.
  • any panel according to the present invention is essentially characterized in that the network of interconnected bosses includes peripheral bosses formed along all the edges of the panel and internal bosses extending from the corners of the panel or in the vicinity of these corners to converge towards the inside of this panel, and in that no boss extends alone, in a straight line, between any two edges, or between two non-neighboring corners, or between an edge and a corner not neighboring the panel, panel, because of its structure, being rigid, self-supporting and designed to withstand forces applied perpendicular to its surface and to transmit them to support points with which it is in contact at or in the vicinity of its corners.
  • the internal bosses are curved and, for example, they meander on the surface of the panel.
  • Another possible characteristic of the bosses is their twisted profile.
  • the bosses preferably have a curved section.
  • all of the areas located between the bosses can constitute a planar or non-planar surface.
  • the panels of the first category called flat panels, can in particular be triangular, square or rectangular.
  • the panels of the second category have a structure which results from a topological transformation of said planar polygonal panels. It has been found that the panels of the second category have static properties equal, if not superior, to those of the aforementioned flat panels.
  • left surfaces such as conoid surfaces, in particular the hyperbolic paraboloid surfaces (PH) well known in architecture, also spherical, ellipsoidal, ovoid surfaces, as well as developable surfaces such as cylindrical or conical surfaces.
  • PH hyperbolic paraboloid surfaces
  • the present invention relates firstly to a polygonal panel 1, for example triangular, square or rectangular, specially designed to withstand forces applied perpendicular to its surface (that is to say, with reference to Figures 1, 4 and 12 for example, perpendicular to the plane of the drawing sheet), and to transmit these forces to support points (not shown) on which the panel is supported by its corners 1a, 1b, 1c, 1d.
  • a polygonal panel for example triangular, square or rectangular, specially designed to withstand forces applied perpendicular to its surface (that is to say, with reference to Figures 1, 4 and 12 for example, perpendicular to the plane of the drawing sheet), and to transmit these forces to support points (not shown) on which the panel is supported by its corners 1a, 1b, 1c, 1d.
  • This panel consists of a layer of substantially constant thickness of a rigid material such as a metal such as steel or a rigid polymeric material, having bosses 2, 3 with hollow section ( Figures 19, 20, 22) intended to increase the rigidity, these bosses delimiting, at least partially, areas 4 which are flat and substantially coplanar.
  • a rigid material such as a metal such as steel or a rigid polymeric material
  • the set of bosses 2, 3 comprises on the one hand peripheral bosses 2 formed in the vicinity of all the edges of the panel, preferably so as to connect all the corners 1a, 1b, 1c, 1 d of the panel, and on the other hand internal bosses 3 extending, in the vicinity of the corners of the panel, or exactly from these corners, towards the interior of the panel, that is to say so approach the center 5 of this panel.
  • These internal bosses 3 form a network of interconnected bosses having a substantially constant distribution density on the surface of the panel, this regularity of density being recognized in that there is no flat area 4, totally delimited by bosses, of which the surface reaches half that of the panel.
  • the panel has a symmetry of order 2 (rectangle), of order 3 (equilateral triangle), of order 4 (square), etc.
  • the distribution of the surface areas similar to very preferably a symmetry respectively of order 2, of order 3, of order 4, etc. It can however also be adequately provided, for any panel having a symmetry of order at least equal to 3, that the distribution of the ranges analogues has a symmetry of multiple or infinite order, and, for any panel having a symmetry of order at least equal to 6, that the distribution of the analogous ranges has symmetry of order under multiple.
  • the network formed by the internal bosses 3 is such that no rectilinear boss extends entirely between any two edges of the panel, or between two non-neighboring corners of the panel, or between an edge and a corner not neighboring this same panel.
  • FIGS. 1 to 18 represent different embodiments of rigid panels.
  • FIGS. 23 to 31 illustrate typical counterexamples of the invention, that is to say panels having a rigidity markedly less than that presented by the panels of FIGS. 1 to 18.
  • the panel of FIG. 23 does not belong to the invention, since it has at least one rectilinear boss extending from a corner of the panel or from its immediate vicinity to a non-neighboring side or to its immediate vicinity;
  • the panels of FIGS. 24, 26, 28, 30 do not belong to the invention, because they have at least one rectilinear boss extending between any edge of the panel or its immediate vicinity and another arbitrary edge or its immediate vicinity ;
  • the panels of Figures 27 and 29 do not belong to the invention because they have at least one rectilinear boss extending between a corner of the panel or its immediate vicinity and a non-neighboring corner, or its immediate vicinity;
  • the panels of Figures 25, 26 and 31 do not belong to the invention because the internal bosses are not interconnected, that is to say at least extremely close.
  • the bosses in the center of the panel are not crossed when these bosses are rectilinear; on the other hand, as shown in FIG. 8, the crossings, in the center, of bosses with sinuous path are quite permitted.
  • Figures 19 and 20 which are sectional views along lines IXX and XX respectively of Figure 4, show that the panels of the invention can be glued or welded, by their side showing the inside of the bosses, on a flat plate 6 of an inextensible and preferably also rigid material, such as plywood, steel, a polymeric substance, etc.
  • This plate can also be formed by another panel according to the invention.
  • the bosses can have a twisted profile. This characteristic makes it possible to increase the torsional resistance of the bosses and, consequently, the rigidity of the panel.
  • the invention also relates to panels such as those shown in FIGS. 32 to 35 and the structure of which results from a topological transformation of a planar polygonal panel having the characteristics of bosses recalled above. (The bosses have not been shown in these figures so as not to complicate them.
  • the panels ABCD according to FIG. 32 and ABC according to FIG. 33 are panels with a surface PH whose contours are projected respectively in a square and a triangle; in other words, we can consider that their structure results from a topological transformation of plane panels respectively A i BC i D and DB I C, the bosses of these plane panels also undergo the same transformation.
  • FIG. 34 shows a panel ABCDEF with a left surface, each half of which (ABEF and BCDE) is a surface PH which projects along a trapezoid (A 1 BE 1 F and BC 1 DE 1 ).
  • the spherical panel ABC (figure 35) projects according to an equilateral or isosceles triangle.
  • each elementary panel is a self-supporting structure and the complex assemblies which they make it possible to create are therefore self-supporting.
  • Figures 36 and 37 show assemblies respectively in tablecloth and in half-cylinder of panels with PH surface with diamond projection .
